3172 Models -002, -003 and -390 Layout

Sort of reminds me of the aftermath of a RS/6000 and a 9595 crash.

The illustrations in the Maintenance manual show the single serial/single
parallel 95 planar. The Model 001 uses an 8580-Axx planar, with (2) 4MB
planar memory cards.. The -002 uses possibly the G complex. The -003 uses
the G but could be upgraded with the M, P, Q and Y.

For ICP, the keypad is used to review error information and to issue
commands. Using the keypad, you can key in a command or request additional
information about any status condition shown on the 4-digit display. The
keypad has 16 keys, hexadecimal numbers 0 through F.

There are four keys on the operator panel that are defined by the ICP:
Channel 1 On/Off Toggle
Channel 1 adapter online and offline.
Channel 2 On/Off Toggle Channel
2 adapter online and offline.
Clear If you make a mistake
keying in a command and want to start again.
Enter Use this key to confirm
an entry.

If you are running ICP, the 66 Mhz processor requires ICP Version 3
Release 3. Previous releases of ICP are not supporter.
The 50 Mhz processor requires at least ICP Version 3 Release
2.

3172 Interconnect Controller Model 1.This was a new product designed to supersede the earlier 8232 LAN Channel
Station. Now withdrawn, the Model 1 was the first of this family of LAN/Host
gateways. It featured an 80386 processor and an IBM Micro Channel* Architecture
supporting up to four LAN adapters and two host channels. In addition,
this model had the capability for remote channel-to-channel services.
Oriented to TCP/IP connectivity, the Model 1 was initially
designed to be used with the Interconnect Controller Program (ICP) Version
1. It is rack mountable in an industry standard 19" rack, such as the IBM
9309. All controls are on the front panel.
It has a wierdly mounted low profile 3.5" DBA drive, WDL-330RS.
The drive is directly mounted to a Type 5 form factor card. The card has
an odd beige colored 4 pin plug, same color as the 8580 power plug.Only
one trace seems to be connected, bet it's the +12v...
The 3172 model 1 requires 200vac-240vac input voltage.
This model uses.. sigh... an 8580-Axx planar
Looking at the -001
parts list- it shows an 8580 style speaker/battery holder...

3172 Interconnect Controller Model 2 The product gained SNA capabilities as well as an FDDI
interface. Performance was slightly enhanced as well with the release of
ICP Version 2. A major change was the introduction of the Operator Facility/2
(OF/2) utility. This filled the requirement for a more robust interface
for the configuration and installation of ICP. Based on the Presentation
Manager of OS/2, it utilizes NetBIOS for communication with the 3172 over
a token-ring or Ethernet connection. OF/2 is a convenient, flexible tool
for managing up to sixteen 3172s from a single workstation. The model 2
has a switchable power supply and will accept 110vac or 220vac.

3172 Interconnect Controller Model 3The Model 3 was announced in June of 1992. As of publication of this
manual it is the current model shipping from IBM. Similar in nature to
its predecessors, the Model 3 surpasses them in performance and in available
options. A new design with enhanced RAS (Reliability, Availability and
Serviceability) characteristics, it features an Intel** 25 MHz 80486SX
processor on a pluggable processor card as standard equipment with 50 MHz
80486DX and 66 MHz Pentium** upgrade options. The Model 3 has a 1.0GB SCSI
disk drive option, extendable memory up to 64MB and for the first time
gains direct wide area connections through the IBM Micro Channel Wide-Area
Connector card to a public or private frame relay network or leased line
SDLC network through the ARTIC Portmaster* card options. The Model 3 offers
a greater span of options and at lower cost than the Model 1. Both the
original Model 1 and the Model 2 have now been withdrawn and superseded
by the Model 3.
The 3172 models 3 requires 200vac-240vac input voltage.
Model 3 featuresThe high-performance hard disk adapter is shipped with the hard disk
and plugs into the system board (into slot 8) (Ed.
Possible error); it provides a receptacle for the hard disk drive cable.
The hard disk adapter that is provided as base hardware is shipped with
the base hard disk.

Single inline memory modules, or SIMMs are plugged into the memory slots
on the system board. There are two banks with four memory slots each on
the system board. SIMMs are shipped and installed in pairs; that is, one
is plugged into slot A1 of the first bank and one into slot B1 of the second
bank. The next two SIMMs are plugged into slots A2 and B2 of each bank,
and so on.

Two 4-MB non-ECC SIMMs are included as base hardware with the IBM 3172
Model 3. Hardware Package1 and Hardware Package2 provide pairs of larger
capacity SIMMs to replace the 4-MB ones. Also, pairs of 4-MB non-ECC SIMMs
or of 8-MB ECC SIMMs may be ordered as features. See "3172 Model 3 Features"
in topic 1.2.2 for more nformation.

The diskette drive uses a standard double-sided, high-density 3.5-inch
removable diskette. The drive motor is +12 volts direct current (V dc),
direct drive (nonbelt). The +12 V dc motor is hardware-controlled and is
switched on only when drive access is required.

The operator panel contains the display, indicators, keypad, defined
keys, diskette drive, and on/off switch. The control logic for reading
the keypad switches and writing data to the status indicators is contained
on the operator panel. The processor logic reads and writes to the operator
panel through the I/O data bus.
